Great game. I would recommend going all out for the sniper rifle at the beginning. The wildlife is fast when spooked and its hard to get in close enough with assault rifles and pistols. Without the animal skins early to upgrade your backpack size and gun holsters its impractible to go hunting human as only having one gun unlocked doesn't hold enough ammo to stack the odds in your favour.

Dont waste your money on weapons. Activate radio towers and they will unlock for free. Get holsters and ammo pouches first. Silent weapons are your friends. I use the bow, Assault rifle and Snifle alot. I never run and gun.
